MANUFACTURE OF CUTLERYa SPECIFICATION forming part of Letters Patent No.274,318, dated March 20, 1883.

' Application filed July lS, 1882. (No model.)

To all whom it may concern Be it known that I, HAD R HALLsTRoM, ofEskilstuna, Sweden, have invented a certain new and useful Improvementin the Manufaca welding them together and to the knife or arof the samebetween the dies.

ticleitself, whereby a strong, durable, and light handle is formed,which cannot become detached from the knife or other article.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a plan view of the handle-blank. Fig. 2 is a longitudinalsectional elevation of the same, showing it pressed between the dies.Fig. 3 is a cross-sectional. elevation of the pressed blank and thedies. Fig. 4 is a plan tndinal elevation of the blank for the knife orother article of cutlery. Fig. 6 is a longitudinal'sectional elevationof the same between the dies. Fig.7 is a cross-sectional elevation Fig.8 is a longitudinal elevation of the pressed blank. Fig. 9 is alongitudinal elevation of the completed knife or fork between the dies.Fig. 10 is a cross-sectional elevation of the same.

r A blank, to, of sheet-iron or steel, is placed between two dies,A andB, and hollowed out or concaved, and the concaved part is then punchedout of the blank. In the same manner one end of a long blank, b, whichhas the length of the knife or fork, &c., is placed between the dies 0D, is hollowed or concaved by the dies, and is then punched out on thedotted line. The pressed handle blank a, or

the handle-blank I), must be a right-hand 5 blank and the otheraleft-hand blank, so that when the open sides of the blanks are placedtogether a hollow handle will be formed, onehalf of which is madeintegral with the knife or fork itself. The two handle-blanks, havingbeen placed against each other in the manner described, are then heatedto the welding-heat. and are placed between two dies, E and F, and aresubjected toblows or to pressure between the dies, whereby the twohandle-blanks will be welded together, and will form a hollow handleintegral with the knife, fork, or other article. It is evident that bothhandle blanks can be made out of short strips of metal, and the two canboth be Welded to the blade. After having been welded, the knives,forks,&c., and their handles, are finished, ground, and polished. Light,strong, and durable handles can thus be made very easily and rapidly,and they cannot become separated from the knife or fork. I Handles forscrew-drivers, chisels, gimlets, draw-knives, 860., can also be formedin the manner described above. view of thepressed blank. Fig. 5 is alongi- I am aware that it is not new to out out the blanks from sheetmetal,or cast them into the desired form and then braze or solder themtogether ;but

What I claim is- The method of forming hollow metallichandles on knivesor forks which consists in first HADAR HALLSTRUM.
